OEX Air Conditioning Compressor 12V Direct Mount Sanden SO7150 Style CXI1551

The OEX air conditioning compressor CXI1551 is a 12V direct mount unit in Sanden SO7150 style, supplied as an individual compressor for vehicle climate control applications. It uses an 8 groove pulley section, a 119mm clutch diameter, and a vertical O ring fitting type, so the mounting style and hose connection arrangement should be checked carefully before ordering.

This compressor is listed with an oil capacity of 240ml and uses PAG46 oil. The note also specifies O rings to suit ORX008 and ORX010, which is important when matching the compressor to the existing A/C pipework and seals. Weight is listed at 7.86kg, and the unit does not include a dust cover.

Fitment information supplied with this part includes Kenworth applications such as C509, K200 and T909 with ISX14.9L from 01/2011 onwards, C510 with QSK 19L, K100E/L700 60 Series 14.0L from 01/1989 onwards, and T350 ISC 8.3L plus C508/K104B ISX 14.9L from 01/2003 to 01/2008. Universal applications are also referenced, so part number and mounting details remain the safest checks before purchase.

Application and Buying Notes

Before ordering, compare the part number CXI1551, the SO7150 series, and the direct mount layout with the compressor already fitted to the vehicle. The 12V electrical setup, 8 groove pulley, 119mm clutch diameter, and vertical O ring fitting type all need to line up with the existing installation for a sensible match.

Fitment is strongest where the vehicle model, engine, and date range all align with the supplied applications. The Kenworth references cover several combinations, including ISX14.9L, QSK 19L, ISC 8.3L, and 60 Series 14.0L engines across the stated build periods. If any of those details do not match your vehicle, use the part number and physical mounting checks rather than relying on model name alone.

This compressor is supplied as a single each unit and weighs 7.86kg, so it is worth confirming you are replacing the correct component and not just a pulley, clutch, or rear head assembly. Matching the gauge line at 49mm and the vertical O ring connection style can save time and reduce the risk of ordering a compressor that looks similar but does not suit the vehicle.

The two year warranty provides a clear reference point for the product, but it does not replace proper system diagnosis. A compressor can be correct on paper and still fail if the receiver drier, condenser, hoses, or expansion device are not in good condition. Careful inspection of the whole air conditioning system is the practical way to protect the replacement part and the repair time.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number CXI1551 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
